This isn't your average park and grab just like the title says, so no point in lifting the skirt of the lamp post this is no 3.5 star L.P.C.
I would describe the container but no point because that would ruin the hint so give it a try, if you have no luck just direct message me and I will see what I can do to mabey guide you in the way of the answer.
Good luck you amazing cahers I know you will find it.
